Description
"Drehmoment- und Massenausgleichssystem für den Antrieb von Kaltpilgerwalzwerken""Torque and mass balancing system for driving Cold pilger mills "
Die Erfindung betrifft ein Drehmoment- und Massenausgleichssystem für den Antrieb von Kaltpilgerwalzwerken.The invention relates to a torque and mass balancing system for driving cold pilger mills.
Drehmoment- und Massenausgleichssysteme, die die durch die zyklische Beschleunigung und Abbremsung des Gerüstes des KaItpilgerwalzwerkes hervorgerufenen nachteiligen Drehmomente kompensieren, sind beispielsweise in den US-PSn 2 924 106 und 3 593 beschrieben. Bei einem bekannten System ist ein Paar Verbindungsstangen (Pleuelstangen) zwischen dem Gerüst und dem Gegengewicht vorgesehen, wobei das Gegengewicht selbst in einer Grube angeordnet und durch ein Paar Verbindungsstangen mit der Kurbel verbunden ist, ähnlich den beiden Ausbildungen in der US-PS 3 335 593.Torque and mass balancing systems, which are caused by the cyclical acceleration and deceleration of the stand of the KaItpilgerwalzwerkes Compensating for disadvantageous torques caused are, for example, in US Pat. Nos. 2,924,106 and 3 593 described. In one known system there is a pair of connecting rods (connecting rods) between the frame and the counterweight provided with the counterweight itself located in a pit and connected to the crank by a pair of connecting rods is connected, similar to the two forms in U.S. Patent 3,335,593.
Ein derartiges System erfordert eine ungewöhnlich große Grube zur Aufnahme des Gegengewichts, wodurch die Kosten für das Walzwerk ebenso wie durch die langen Verbindungsstangen erhöht werden, Darüberhinaus ergeben sich zahlreiche Probleme bei der Instandhaltung dieser Systeme.Such a system requires an unusually large pit to hold the counterweight, adding to the cost of the rolling mill as well as increased by the long connecting rods, In addition, there are numerous problems with the maintenance of these systems.
Es ist daher die Aufgabe der Erfindung, ein Drehmoment- und Massenausgleichssystem zu schaffen, das nicht nur für Kaltpilgerwalzwerke sondern für alle hin- und hergehenden Massen Verwendung finden kann und das sowohl die Konstruktion vereinfacht, wie auch die Kosten verringert.It is therefore the object of the invention to create a torque and mass balancing system that is not only suitable for cold pilger mills but can be used for all reciprocating masses and that simplifies the construction, as well as reduced the cost.

Es ist daher die Aufgabe der Erfindung ein Drehmoment- und Massenausgleichssystem zu schaffen, das nicht nur für Kaltpilgerwalzwerke sondern für alle hin- und hergehenden Massen Verwendung finden kann und das sowohl die Konstruktion vereinfacht, wie auch die Kosten verringert.It is therefore the object of the invention to provide a torque and To create a mass balancing system, not only for cold pilger mills but can be used for all reciprocating masses and that simplifies the construction, as well as reduced the cost.
Gelöst wird diese Aufgabe erfindungsgemäß durch die im Hauptanspruch angegebenen Merkmale.This object is achieved according to the invention by the main claim specified features.
Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.Further refinements emerge from the subclaims.
Durch die erfindungsgemäße Lösung ist das Gegengewichtsystem direkt und ohne Verbindungsstange mit der Kurbel verbunden.With the solution according to the invention, the counterweight system is connected to the crank directly and without a connecting rod.
Die Erfindung soll nachfolgend anhand des in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert werden. Dabei zeigt:The invention is to be explained in more detail below with reference to the exemplary embodiment shown in the drawings. Included shows:
Fig. 1 eine perspektivische schematische Ansicht des Kaltpilgerwalzwerkes undFig. 1 is a perspective schematic view of the cold pilger rolling mill and
Fig. 2 einen Schnitt durch den Antrieb gemäß Fig. 1FIG. 2 shows a section through the drive according to FIG. 1
In der Figur 1 ist schematisch ein Kaltpilgerwalzwerk und dessen Antrieb dargestellt. Auf eine detailierte Erläuterung des Walzwerkes selbst wurde verzichtet, da die Einzelheiten allgemein bekannt sind.In the figure 1, a cold pilger mill and its drive is shown schematically. To a detailed explanation of the rolling mill itself was omitted as the details are well known.
Das Walzwerk 10 weist ein Gerüst 12 auf, in dem sich die Walzen 14 befinden. Das Gerüst 12 wird in Richtung des Rohrweges durch parallel angeordnete Führungen 16 geführt.The rolling mill 10 has a stand 12 in which the rolls 14 are located. The framework 12 is in the direction of the pipe path through guides 16 arranged in parallel are guided.
Die Bewegung des Gerüstes wird erfindungsgemäß durch eine einzige Verbindungsstange bewirkt, deren eines Ende am unteren Teil des Gerüstes 12 und deren anderes Ende am Kurbelsystem angelenkt ist.The movement of the scaffold is effected according to the invention by a single connecting rod, one end of which is at the lower part of the Scaffolding 12 and the other end of which is hinged to the crank system.

Ein Kurbelsystem mit einem Gegengewicht ist als solches bekannt, aber die Erfindung stellt eine Verbesserung der Kurbel und des Gegengewichtes dar, so daß man mit einer einzigen Kurbelwellenkröpfung und Verbindungsstange auskommt.A crank system with a counterweight is known as such, but the invention represents an improvement of the crank and the Counterweight, so that you can get by with a single crankshaft offset and connecting rod.
Wie sich aus den Figuren 1 und 2 ergibt, ist eine vertikale Antriebswelle 20 für das Kurbelsystem vorgesehen. Die Kurbel ist mit 22 bezeichnet und horizontal angeordnet und am inneren Ende ist ein als Segment ausgebildetes Gegengewicht 24 befestigt. Am unteren Ende der Welle 20 ist ein Kegelrad 26 angeordnet, das von einem Kegelrad 28, das mit einem elektrischen Motor 30 verbunden ist, über einen Riemen 32 angetrieben wird.As can be seen from Figures 1 and 2, there is a vertical drive shaft 20 intended for the crank system. The crank is denoted by 22 and is arranged horizontally and at the inner end a counterweight 24 designed as a segment is attached. At the lower end of the shaft 20, a bevel gear 26 is arranged, which of a bevel gear 28, which is connected to an electric motor 30, is driven via a belt 32.
Die horizontale Anordnung der Kurbel 22 ermöglicht es, daß ein Block 32 mittels eines Stiftes 34 an der Kurbel befestigt werden kann.The horizontal arrangement of the crank 22 enables a block 32 to be attached to the crank by means of a pin 34 can.
Der Block 32 befindet sich in einem Schlitz 36 in einem zweiten Block 38.The block 32 is located in a slot 36 in a second block 38.
Der Block 38 ist entsprechend der Lehre der vorher genannten US-Patente um 90° phasenverschoben mit der Kurbel angeordnet und die hin- und hergehende Bewegung erfolgt in Richtung der Pfeile 40, bei Drehung der Kurbel 22 in Richtung der Pfeile 42 durch ein Paar parallele Führungen 44.The block 38 is in accordance with the teaching of the aforementioned US patents Arranged out of phase by 90 ° with the crank and the back and forth movement takes place in the direction of the arrows 40, upon rotation of the crank 22 in the direction of the arrows 42 through a pair of parallel guides 44.
Aus den obigen Ausführungen ergibt sich, daß das Kurbel und Gegengewichtssystem sehr kompakt ist. Im Betrieb arbeitet das Kurbel- und Gegengewichtssystem ähnlich den in den obigen US-Patenten dargestellten Gegengewichten. Das Gegengewicht macht eine oszillierende Bewegung, wobei der Zyklus im wesentlichen gleich dem der Kurbel ist, aber um 90° phasenverschoben zu der Kurbel, wodurch die Masse und die Drehmomente des Walzwerkes 10 ausgeglichen werden.From the above it can be seen that the crank and counterweight system is very compact. This works in operation Crank and counterweight system similar to the counterweights shown in the above U.S. patents. The counterweight makes one oscillating movement, the cycle being substantially the same as that of the crank, but 90 ° out of phase with the crank, whereby the mass and the torques of the rolling mill 10 are balanced.
